Yes, the Ella fast-fill faucet sets are available on their own, and people do ask about fitting one to a tub that is not an Ella. What Ella cannot do is confirm that the set will fit another brand's tub. The team has not seen that tub's deck, hole layout or plumbing, so whether it works is a decision for you and your contractor, made against the published specifications for the faucet. Order the set through your Ella dealer or the team at (800) 480-6850 so you receive the current genuine set with its specs.

What the Faucet Needs from the Tub

Both fast-fill sets are deck-mount faucets designed for high flow. The 2-piece set fills at 16 gallons per minute and the 5-piece set at 18 gallons per minute, and both come with 5 foot supply lines. The deck must have the right number of holes at the right diameter and spacing, with enough flat surface for each base to seat and seal. Set details are in buying a fast-fill faucet set or valve body on its own. Compare those specifications to the tub you have before ordering, or ask your contractor to do it.

What to Think Through with Your Contractor

  1. Confirm that the hole count, diameter and spacing on the existing deck match the set, or that the deck can be drilled to suit.
  2. Plan how the supply lines will reach the faucet. On a sunken or concrete-set tub the space below the deck may be limited, and the lines have to be routed before the tub is enclosed.
  3. Plan for service access. The valve body and supply connections need to be reachable later for a cartridge change or a supply line replacement, which is a real concern when a tub is set in concrete.
  4. Check that the home's supply can deliver the flow the faucet is built for. A fast-fill faucet only fills fast when the supply keeps up with it.

Supply line sizes and thread types are in replacement hot and cold faucet supply lines, and the mechanical steps in replacing a faucet set or hand mixer apply to the install regardless of which tub it goes on.

Support and Warranty on a Non-Ella Tub

Ella's technical support can answer questions about the faucet itself. Problems that come from the other tub's deck, drilling or plumbing are for your contractor to resolve, and the team will not advise one way or the other on whether a particular non-Ella installation is a good idea. The published exceptions that apply to faucets are in warranty exceptions for the TCV and faucets. If you are not sure whether your existing tub is an Ella, identifying the brand and model from labels, doors and faucets walks through what to look for, and what can and cannot be customized covers faucet choices on a new Ella tub.

Common Questions

Can I buy the 5-piece faucet without buying a tub?
Yes. Both the 2-piece and 5-piece fast-fill sets are available on their own through your Ella dealer or the team at (800) 480-6850. Ordering that way is the sure way to receive the current set that matches the published specifications.
Will the Ella faucet fit my existing non-Ella tub?
Ella cannot confirm fit on another brand's tub because the team has not seen its deck or plumbing. Compare the faucet's published specifications to your tub, and let your contractor make the call.
Is the 5-piece set faster than the 2-piece set?
Yes. The 5-piece set fills at 18 gallons per minute and the 2-piece set at 16 gallons per minute, and both ship with 5 foot supply lines. Actual fill time also depends on your home's water supply.
Can I install it on a sunken concrete tub?
That is a decision for you and your contractor. The two things the team asks you to plan for are how the supply lines will reach the faucet and how the valve body will be reached for future service once the tub is enclosed in concrete.
Who supports the faucet after it is installed elsewhere?
Ella can answer questions about the faucet itself and its published warranty exceptions apply. Issues caused by the other tub's deck, drilling or plumbing are handled by your contractor. Keep your order details so the team can identify the set if you need a part.
